Would you please post your attempt at using the BrowserFrame object in your tkinter program and any error information?

This code really belongs in class MainFrame.__init__

highlightthickness=2)
left.grid(row=0, column=0, rowspan=99, sticky='ne', pady=2)

home_browser.grid(row=0, column=1, rowspan=99, sticky='ne', pady=2)
right = tk.LabelFrame(app, text="", padx=5, pady=5, highlightbackground="black",
highlightthickness=2)
right.grid(row=0, column=2, rowspan=99, sticky='ne', pady=2)left is placed in the same grid cell as navigation_bar
left.grid(row=0, column=0, rowspan=99, sticky='ne', pady=2)
self.navigation_bar.grid(row=0, column=0,
sticky=(tk.N + tk.S + tk.E + tk.W))I don't know, but think this may be your main problem because it removes the Navigation bar, and thus the browser, from the MainFrame. As mentioned in the comments in get_window_handle, the MAC version is kind of brittle and it is easy to make it crash.

That is the error message you are getting when your program crashes.
Why are you setting rowspan=99? Is that a sloppy way to say "I am the only thing in this column?" Sloppy meaning imprecise, not bad. Maybe bad.

Even thou how do i implement it in my project?
for example this is one of two places were i need a browser window
from tkinter import *
from tkinter import ttk
import tkinter as tk
from formularios import tabmain0
import requests
from bs4 import BeautifulSoup
import webbrowser
import tkinterweb
def home():

log_error(e, "Bookmark_Builder")
container.pack(expand=1, fill="both")
scrollbar_x.pack(side="bottom", fill="x")
scrollbar_y.pack(side="right", fill="y")
canvas.pack(side="bottom", fill="both", expand=True)here you can see a working example with tkinterweb, unfortunally this browser module dont read most of the websites.
i would be perfect if i could have a function to call, something like, open_browser(frame_name, url)

Put the example somewhere in your python path so you can import NavigationBar. I recommend the same directory as the other python files for the project. Create your tkinter app and make a frame that will contain the browser (home_browser from your example), then just make a NavigationBar that will be the only object in the frame. If you don't want the navigation bar create an instance of BrowserFrame instead.
If the browser does not appear in browser_frame it is probably because the browser_frame is not resizing or because browser_frame is not resizing it's contents.
